In response to multiple crashes that resulted in death or serious injury, the City of Pittsburgh's Department of Mobility and Infrastructure's Vison Zero team has been working with local stakeholders including University of Pittsburgh, UPMC, and the community to redesign Terrace Street and De Soto Street between Robinson St and O'Hara St to calm traffic, improve safety, and better protect vulnerable road users – pedestrians and cyclists.

Following up the "rapid response safety changes" of signal adjustments and new crosswalks that were implemented in January-March 2025 and stakeholder meetings that were held in June, the project design phase was completed in July-August with design recently finalized in August. Draft corridor plans are available on the City's EngagePGH page dedicated to this traffic calming project.

The project includes new pedestrian crosswalks on Dunseith at Terrace, across Chesterfield at Terrace, and across Buffalo at Terrace, as well as new bumpouts (painted lines) and flex posts added at Terrace & Dunseith, at the small driveway located just uphill from Dunseith at Terrace, at Terrace & Darragh, and at Terrace & Chesterfield (where a pedestrian refuge island will also be added on Terrace.)

According to the City's EngagePGH portal, this quick-build Vision Zero project will calm traffic primarily by narrowing the roadway and using the extra space created to add bike lanes in both directions of Terrace between Darragh to O'Hara.

For cyclists, the new eastbound bike lane on Terrace approaching De Soto will be parking-protected, which will narrow the roadway for motorists. The uphill climbing lane on De Soto will be buffered with vertical elements, further narrowing the roadway for motorists.

Bump-outs with vertical elements (flex posts) designed to keep cars from illegally parking near intersections will ensure clear sight-lines and slow turning vehicles as they approach intersections. The narrower roadway will also create shorter crossing distances for pedestrians to improve safety.
